Front spring SZR660

【HYPERPRO 22031170 Front Spring SZR660 Suspension Fork Spring】
■Front Spring
Suspension spring with constant rising rate uniquely designed by Hyperpro.
The spring rate constantly changes in response to the suspension's movement.
It maintains a state that is neither too soft nor too hard, and also has the ability to maintain stability during high-load cornering and sudden braking.
●Optimizes caster changes during braking before corners, making it easier to transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike ordinary springs, there is no constant spring rate, so there is no resonance.
●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic scratches on the surface that lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection using a tester.
●In Hyperpro's home country of the Netherlands, all emergency motorcycles are equipped with Hyperpro springs.
